Nā kikoʻī maʻamau
API 5Lpili maʻamau i ke kūlana hoʻokō no nā paipu kila pipeline. ʻO nā paipu kila paipu me nā paipu kila ʻole a me nā paipu kila welded. I kēia manawa, ʻo nā ʻano paipu kila welded maʻamau ma nā paipu aila, ʻo ia ka spiral submerged arc welded pipe (SSAW), straight seam submerged arc welded pipe (LSAW), a me ka uila kū'ē i ka welded pipe (ERW). ʻO nā paipu kila ʻole ke koho ʻia inā ʻoi aku ka liʻiliʻi o ke anawaena o ka paipu ma mua o 152mm.
ʻO ka pae aupuni GB / T 9711-2011 ʻO nā paipu kila no ka ʻaila a me ka ʻoihana ʻoihana pipeline ʻōnaehana kaʻa i hōʻuluʻulu ʻia ma muli oAPI 5L.
Hōʻike ʻo GB / T 9711-2011 i nā koi hana no nā paipu kila ʻole a me nā paipu kila welded ma nā pae kikoʻī huahana ʻelua (PSL1 a me PSL2) i hoʻohana ʻia i ka ʻaila a me ka ʻoihana ʻoihana pipeline transport system. No laila, pili kēia maʻamau i nā paipu kila ʻole a me nā paipu kila welded no ka lawe ʻana i ka aila a me ke kinoea, a ʻaʻole pili i nā paipu hao.
Papa kila
ʻO nā māka kila waiwai maka oAPI 5Lnā paipu kila me GR.B, X42, X46, X52, X56, X60, X70, X120 pipeline kila. ʻO nā ʻano kila like ʻole o nā paipu kila he ʻokoʻa nā koi no nā mea maka a me ka hana ʻana, akā mālama pono ʻia ke kalapona like ʻole ma waena o nā pae kila like ʻole.
Kūlana Kūlana
I ka API 5L paipu kila, ua māhele ʻia nā kūlana maikaʻi (a i ʻole nā ​​koi) o nā paipu kila i PSL1 a me PSL2. ʻO PSL ka pōkole o ka pae kikoʻī huahana.
Hāʻawi ʻo PSL1 i nā koi pae maikaʻi o ka pipeline steel pipeline; Hoʻohui ʻo PSL2 i nā koi koi no ka haku mele ʻana, ka paʻakikī notch, nā waiwai ikaika a me ka NDE hou.
ʻO ka pae paipu kila o ka paipu kila PSL1 (inoa e hōʻike ana i ka pae ikaika o ka paipu kila, e like me L290, 290 e pili ana i ka ikaika haʻahaʻa haʻahaʻa o ke kino paipu he 290MPa) a me ke kila kila (aiʻole ka pae, e like me X42, kahi. 42 hōʻike i ka ikaika hāʻawi liʻiliʻi a i ʻole ka pōʻai i luna ʻO ka ikaika haʻahaʻa haʻahaʻa o ka paipu kila (i ka psi) ua like ia me ka paipu kila Ua haku ʻia me nā leka a i ʻole nā ​​helu hui ʻia o nā leka a me nā helu e ʻike ai i ka pae ikaika o ka paipu kila, a ua pili ka papa kila i ka hana kemika o ke kila.
ʻO nā paipu kila PSL2 i haku ʻia me nā leka a i ʻole ka hui pū ʻana o nā leka a me nā helu i hoʻohana ʻia e ʻike i ka pae ikaika o ka paipu kila. ʻO ka inoa kila (steel grade) e pili ana i ka hana kemika o ke kila. Aia pū kekahi leka hoʻokahi (R, N, Q a i ʻole M) i kahi suffix, e hōʻike ana i ke kūlana hoʻopuka. No ka PSL2, ma hope o ke kūlana o ka lawe ʻana, aia pū kekahi leka S (kahi o ka lawelawe ʻana i ka waikawa) a i ʻole O (kahi lawelawe kai moana) e hōʻike ana i ke kūlana lawelawe.
